Global Warming is the increase of temperature on Earth which is caused by
human activities and will have very serious consequences for life on Earth if
humans don't start to do something about it now. Global Warming is caused when the
Greenhouse Gases combines with the atmosphere and traps heat. It is strongly related to
pre-human and pre- industrial global warming, it is also weakly related to depletion of
ozone layer, which was caused by the CFC (Chlorofluorocarbons) gas. The effects of
global warming on the environment are dangerous, such as: rising of sea level because
polar caps melt, changes in the pattern of precipitation, floods, droughts, heat waves,
hurricanes and tornadoes. These effects would take away life and destroy houses or
anything else human made. The effects of global warming on humans are also dangerous,
such as: affecting human health by affecting ecosystem and productivity, air quality,
diseases and agricultural production. We could prevent all of these from happening by
using alternative sources, for example: wind, solar, nuclear and water power. With the
help of modern technologies, we could increase the Earth?s reflectivity and keep it cool.
The most important thing is to keep population under control and recycle.
Global Warming is the process where in the Earth is getting warmer and the
atmosphere is getting thicker because the amount of Greenhouse Gases (GHGs) is
increasing. Greenhouse Gases includes carbon dioxide, methane gas, nitrous oxide,
water vapor and CFC (chlorofluorocarbons). These gases (except CFC) are naturally
there in the atmosphere, but too much of them traps too much heat. Even though carbon
dioxide is considered to be the biggest cause of global warming, other gases contribute to
global warming too because some gases are not very big in quantity, but their absorbency
is larger than the others. For instance, Nitrous oxide is the major greenhouse gas and has
296 times the effect of carbon dioxide (www.en.wikipedia.org/wiki/Nitrous_oxide, Feb,
Human activities are the biggest contributor to global warming. Industrialization,
transportation and forest burning releases gases that join the atmosphere and trap heat.
Industrialization has been proved to release high amounts of carbon dioxide since the
Industrial Revolution began in the early 19th century. The total amount of carbon
dioxide has increased by one ? third of the usual amount in the atmosphere.
Transportation uses fossil fuels to run and as a result, it produces gases such as carbon
monoxide and carbon dioxide. Now, in the modern lifestyle, most of the people
want and have private cars. This further increases the amount carbon dioxide released to
the air by the means of transportation. The biggest cause of global warming is forest
burning. This is because when we are burning forests, trees inside it, which usually
absorb carbon dioxide, release lots amount of carbon dioxide....
